fireball spectrum analyzer

Fireball Spectrum Analyzer

Our Multichannel Spectroscopy system with data analysis and associatedelectronics covering wavelength range from 400nm to 1650nm which willbe used to capture some critical data about fireball temperature , fireballduration and fireball constituents. This system will consist of 4 channelswhich will be used for spatial measurement at 4 different positions.The system can also capture signal in a unite way where all the 4 channelswill capture signal individually at single position with even faster samplingtime i.e, 100 usec.

Our multichannel spectroscopic system will consist of onboard datastorage with a capacity of minimum 5000 spectra which is runningwith integration time of less the 30usec. The whole system will beconsist of Silicon (CMOS) & InGaAs detectors , internal & externaltriggering hardware , DAQ with all the centralize software to controlall the light collection optics.

Our Multichannel spectroscopic system will consists of the following sub-systems:1. Spectroscopy modules2. Controller with Data acquisition Unit3. Light collection optics with fiber delivery

Our spectroscopy modules are based on Symmetrical Czerny –Turnerwhich has an option of external band filters along with SMA 905 connectorthrough which the intensity can be controlled from 0 to 100%.Also there are

ndsome provision to remove unwanted signal i.e, 2 harmonics which alsoenhances the sensitivity.

Spectroscopy Modules:

Our spectroscopy module will consist of 4 synchronized channels whereeach channel will consist of VIS NIR and NIR spectrometer.

VIS NIR: 400 to 1000 nm, other option as per user requirement.NIR: 1000 to 1650 nm, other option as user requirement

Both VIS NIR and NIR spectrometer have solution to work together in Synchronize mode with each other as well as independently.
